COMPQANY, DE CLEVELAND, OHIO, A CORPORA- BARREL JOINT.

Application filed February 1a, 1921. Serial No. 44 2,7635;

To all whom it may concern:

Be it known that we, PATRICK J. GUL- HANE, Jr., and LIGUORIA F. Flsnnnr,citizens of the United States, residing at Cleve- 5 land, in the countyof Cuyahoga and State of Ohio, have invented a. certain new and usefulImprovement in Barrel Joints, of which the following is a full, clear,and exact description, reference being had to the no accompanyingdrawings.

This invention relates generally to sheet metal barrels and moreparticularly to the manner of uniting the two sections of which thebarrel is composed. The object of the invention is to provide a brazedjoint that shall be strong, durable and efficient and in which theco-acting parts thereof can be quickly and easily formed and in whichthe completion of the joint can be accomplished with certainty.

Another object of the invention is to provide a construction which willfacilitate the accurate assemblage of the sections into the completedbarrel. Another object of theinvention is to provide a joint of such acharacter that can be made at the same plant where the tub sections areformed or they can be fabricated as tub sections and shipped to anypoint desired and there assembled and joined without the use ofcomplicated or expensive machinery.

With these objects in view the invention consists in the novel featuresof construction hereinafter fully described and set forth in theappended claims.

In the drawings acompanying and forming a part of this specification,Fig. 1 is a side elevation of a barrel constructed in accordance withour invention and Fig. 2 is a detail sectional view showing the mannerof making the joint between the two sections of the barrel.

In the practical embodiment of ourinvention we employ two tub-likesections A and B, the extreme edge A of the section A being broughtfirst inwardly as shown at A and then outwardly as shown at A so as tobring the extreme edge A into such .position that it can be, insertedwithin the edge B of the section B and forced into said section untilthe said edge A makes a line contact with the interior of the section Bat the int B and provide a gradually tapered c annel 13 between the saidedge A and inner face of the sectionB and into between the tub sectionsA and B. The inwardly projecting portion A and A providing apircumferential groove can also be utilized for receiving the brazingcompound preparatory to placing the contracted end of the tub sectioninto the other tub section, said brazing material being in the form of apaste and thereby capable of being packed into the circumferentialgroove so that it will not interfere with the ready insertion of thecontracted edge A into the end of the section B and by maintaining thesections A and B in their proper relative positions with reference toeach other when they are placed together, the line contact B will bemaintained at the proper depth entirely around the entire circumferenceand this line contact will provide ample frictional engagement to enablethe barrel as a whole to be turned within the brazing ring or otherheating apparatus so that the brazing material as it is melted will becaused to fiow completely around the circumference of the barrel andfill the tapering channel as most clearly shown in Fig. 2, therebysecurely connecting the two tub sections together. In the drawing theinterior and exterior portions A and A are somewhat exaggerated, inorder to clearly illustrate the manner of introducing the brazingmaterial and it will be understood that the sections can and will beforced sufiiciently close together to practically close the exteriorjoint between the upper and lower sections and this joint may becompletely closed by galvanizing the entire exterior of the barrel asindicated in dotted lines at B in Fig. 2. It will be understood,however, that this joint may be filled, closed or concealed in anysuitable manner inasmuch as brazing material will eificiently connectthe two sections together upon the interior and inasmuch as a continuousline contact is had between the contracted ed e A. and the interior ofthe barrel, a per ectly tight brazed joint will be insured inasmuch asthere is no possibility of leakage through which metal could escapeinasmuch as the line contact between the parts prevents such leakage. Itwill also bt understood that a very small contraction and inclination ofthe edge A will answer the purpose and in fact any contraction and ofsaid edge and insure the proper line contact will be sufficient.

Y Having thus described our invention,

what We claim is:

1. As a new article of manufacture, a barrel composed of two tub-likesections, the edge of one section being bent inwardly and thenoutwardly, said outwardly bent portion of the edge fitting into the edgeof the opposed section and contacting with the interior thereof andbrazing material uniting the sections together, said brazing materialbeing contained between the edge of one section and the curved edgeportion of the other section.

2. The herein described method of uniting two tub-like sections toprovide a barrel which consists in contracting the edge of one portionsufliciently to fit into the edge of the other portion and at the sametime provide a groove between the contracted edge portion and theopposed edge, inserting the contractededge of one'section into the,other section, filling the intervening space with brazing material anduniting said sections together.

In testimony whereof we hereunto aflix our signatures.

PATRICK J. CULHANE, JR. LIGUORIA F. FISHLEY.
